i have always wanted a plain ole .300 win magnum. But i feel like if i dont go ahead and get the 300 ultra i will be missing out. I currently own a 30-06 7mm-08 7mm ultra mag .325 short mag and of course a 270 win mag. I do take fairly long shots 300-500 500 the absolute longest. I carry my 7mm ultra mag to that deer stand with confidence, but im tring to get where i can trust my .325 this season at those distances also. Such a good looking rifle i cant help but want to use it, plus it does wonders on deer from 100-200 yards so far.

Anyway i like to collect and use different rifles and the .300 is somthing ive always wanted. Im leaning toward the .300 win mag for bullet selection. I do not reload so factory ammo must be plentifull. (Thats a major downfall to my 7rum, but luckily me and my rifle really like the swift siriccos..spelling??...

My questions is, is the factory ammo availablity with the 300 ultra as good as the 300 win? I really like barnes x ammo and of course federal. What all manufactures produce 300 ultra ammo? Thanks alot.

Welcome to the forum 7mm. Rules are simple, be nice and join in.

I've shot both the 308 Norma and the 300 Win mag and there both good calibers, but the new Ultra-mag is really impressive.

Here's a friends at the range.

http://i136.photobucket.com/albums/q172/faucettb/Guns/Dustinatriflerange.jpg

Here's factory ammo with 180 bullets.

http://i136.photobucket.com/albums/q172/faucettb/Guns/Chrono300RUM180Factory.jpg

That's 3380 with a 180 grain bullet, now that's one flat shooting rig.

I have a friend who has a 300 RUM and I can tell you first hand the performance on deer is remarkable. His is a M70 that is super accurate. The next rifle I get will be in 300 RUM. I don't handload so Remington's power level ammo for the ultra mag makes it very versatile. You should check into it if you haven't already. Power 1 is like .30-06 performance, 2 is like 300 Win, and 3 is the regular 300 RUM. In my opinion, this is one of the best new cartridges introduced in the last decade or so. My ultimate rifle is an A-Bolt Medallion chambered in 300 RUM. Browning isn't chambering anything in the RUMs so it just has to wait for now. Second pick would be one of the new M70s but I don't think they will be chambered in the RUMs either. Third would be the 700 in the BDL, CDL, or XCR which by all accounts are good rifles.

7mmbomb,

Welcome to the forum.

You might want to go check the stores in your area that sell ammo since you do not reload. The largest 30 cal in my area I have seen is the 300 win mag. Of course, if you really want the 300 RUM, that would be a good reason to get into the addictive hobby of reloading! With that, you could load from mild to wild!

300 RUM should be at least as plentiful as the 7mmRUM. I see it on sale here all the time for 50% off retail.

The RUMs really walk away from the competition in the 338 caliber, whereas they are only marginal improvement in the 7mm and 300 flavors.

I've got the 300 RUM in a Rem 700. I've never played with the 300 win mag so I can't comment on that, but I can say that I am surely impressed with the 300 RUM's performance.

If you like the Swift Scirocco bullets I know that Remington factory loads these for the 300 RUM in the 150 and 180 gr bullets. Around here you can still find them for around $50 a box. I haven't been to the ammo counter in a while since I reload.

I've got to disagree with you mattsbox99. The best velocity I could get out of my 300 Win mag with 180 grain bullets was 3170 and as you can see the Scirocco bullets out of the 300 Rum is 3384.

That is an impressive improvement over the 300 win. My 308 Norma Mag would top out at the 3150 or so velocity also. My friend whom shoots the 300 RUM has made a bunch of impressive kills well past 600 yards with it. I think it's a hands down improvement on all the short case 300's and most of the long case 300's such as the 300 Weathereby. Or at least my chronograph says. That's like saying the 300 Win mag is not an improvement over the 30-06.

So you guys think i will like the 300 ultra even more than the 7 ultra?? I was comparing ballistics on the remington site and with them both shooting 150 siroccos, it showed the 300 ultra just barely having more energy than the 7 ultra up to 300, out past 300 the 7 ultra started spanking the 300 ultra's but.

Also that ballistic chart showed the 300 ultra just BARELY shooting flatter than the 7 ultra. After comparing those rounds on that chart i later read that the 300 ultra was being shot threw a 20 inch barrel???? (Still confused on why they would use such a short barel.) They used a 24 inch barrel for the 7 ultra. Im going to check on the ammo for the 300 ultra and if i can get federals and barnes x in different grain bullets, i belive ill get the ultra. Now i just need to decide on which rifle i want

I would really like the bdl in the old faithfull shiny wood stock, but ive heard alot of guys tell me that the wood will expand and shrink in different temps, and cause for a little bit of unaccuracy. Anybody have any opinions on that?? Thanks alot for the help.

Went to Rem's website and compared ballistics B/W the 300 RUM and 7mm RUM. Wouldn't call it spanking. I saw something new on the site though. They are now making "power" level loads for the 300 RUM and compare it to different shotshell loads (2.5", 3" and 3.5"). Don't know anything about it and its probably just something to seel more ammunition. Anyway the energy looks pretty much the same out to 500 yards. Don't think that any animal is going to notice the difference of 100 ft-lbs if its anywhere near 2400. Now the 'Power' level 1 does show a bigger gap when compared to the 7 mag.

I've shot the factory loaded 150 gr scirocco's over a chrony and got dang near an average velocity 12' from muzzle of 3675 with the high being over 3700 fps. Seemed a little hot to me but that is what the chrony said.

Your right though the 2 calibers are pretty comparable when loaded with factory ammo, at least according to Remington's ballistics.

The link to the comparison:

http://www.remington.com/products/ammunition/ballistics/comparative_ballistics_results.aspx?data=PR300UM5* PR300UM1-P1*PRSC7UM1

As far as which rifle...

Mine is a Rem M700 SPS. I had the cheap looking stock composit stock taken off and replaced with a HS Precision stock that was bedded and feels alot stronger. I also had the trigger pull lightened and the creep taken out of it by my smith. Put a 6-18 swaro scope on it and can print 3/4 moa all day with my handloaded recipe using 150 grain sciroccos.

Good luck to you in your decision. Do let us know how it turns out.

Edit:

Sorry forgot to post barrel length. It is a 26 in barrel.

I've been shooting the BDL's since 78 with no problems. Five of those years were in Alaska where weather extremes are normal. I would suggest a good glasbed/piller bed job on any wood stock. I would also suggest you tell the guys telling you about the wood stocks that they are full of it. There's sure been lots of wood stocked guns killing lots of game over the last couple of hundred years and in my experience, 27of which I ran a gunsmith shop, that's not a real issue on a properly finished stock and never an issue on a properly finished glass bedded stock.

My friend has a rebuilt 700 with a blue printed action, 28 inch ported barrel and an HS precision stock. With Nosler 180's it's shooting half inch hundred yard groups at just over 3300 fps with handloads. This year he harvested two deer an elk and a caribou all at 500 yards plus. This gun weighs under 7.5 pounds with scope and ammo in it. Recoil falls somewhere in between a 270 and an 06.

If you do go for a plastic stock I'd stay with some of the better brands like HS precision. The injection molded stocks seem to have some forend flex problems that are fairly hard ot solve. I had one on a Rem 700 ML and it was as flexy as a rubber noodle.

As much as I like the 300 magnums I sure wouldn't suggest using the 150 grain bullets in them. Meat damage will be excessive. It didn't take me long to figure that out with my 308 Norma. I got much better results with the 180's.

Right now I shoot an old Remington 8mm mag with the 220 grain Sierra Gameking boattail spitzer at 3080 fps. This is a great round and chambering it out to 8mm Ultra-mag would give me the ability to push that bullet to 3200 fps. Meat damage is usually less than my friends 270's and it kills really well.

If you think the 300 is really walking away, look at the 338... thats all I'm saying, Bob. I've got the 7RUM in a BDL... I like it very much...

well the only companies that make ammo for the 300 ultra is federal and remington, but federal offers a 150grain sonthing, i forgot..and a 180 gain barnes triple shock, exactly what i wanted to shoot.

On the other hand there is TONS of different ammo made for the 300 win. mag. So i still have some thinking to do. Thanks for all the help so far.

I really feel bad for you that you have to buy ammo, and not able to take advantage of reloading... you would seriously save a ton of money in that caliber... and since you shoot more than one caliber, the savings are multiplied even more...

There is really wrong with the Win Mag, as long as you don't mind be slapped around by the RUM :D

I've been watching this thread and I thought I'd add a couple pennies worth here.

I've got a 300RUM in Sendero SFII. I had a 300RUM in 700CDL. I traded the CDL on the Sendero because I wanted the Sendero but they were hard to find so I got the CDL and waited for the Sendero. Between the 2 I couldn't tell you which one had more recoil, I'd say they were pretty even.

I've shot 3 different 300 Win mags, a Winchester M70, a Remington 700 and a Savage. Of the three, the Savage was a bit worse than the Rem or the Win. Comparing the 300WM and the 300 RUM, yes the RUM has more felt recoil but it's a different type of recoil. More of a big push than a jolt.

I've also put loads for both the RUM and the WM across a chronograph. Both using 180 grain bullets. The rum was 300 fps faster than the WM. That equates to flatter and farther in my book. I'm not trying to take anything away from thre 300WM, but it's hard to beat pure horse power. Kinda like comparing a 351 Boss to a 428 Cobra. Either one is going to set you back in the seat, it's just a matter of how far back you want pushed.

I also think that if a shooter takes the time to get to know his rifle, no matter which of the 300's he has, a 500 yard shot is not out of the question. It's the expense of the ammo that will be the detemining factor in how much a guy practices. That's why I reload. 300RUM's at $50 bucks a box of twenty, it wouldn't take very long to pay for a Lee reloading outfit. Even running store boughts through the 300WM at $30+ a box it still wouldn't take very long. As far as running 150's through a 300RUM, it's like putting 85 octane gas in that 428 Cobra. It'll run, but it won't like it. 'Sides, if'n you're going to burn all that gas, you just as well use the good stuff.

To me 180's is as light as I'd go in either the RUM or the WM, even on deer. I've seen what 180's from both rifles will do to elk so I can imagine what they will do to deer size game. A 150 from the RUM would plumb scary to shoot deer with. You might salvage the hind quarters, but the shoulders would be out of the question. Again, with the 180's a guy has a better choice of options as to bullet construction. You've also got a better ballistic coefficent and sectional density with the 180's v.s. the 150's.

Hmm, looks like my 2 cents tuned into a quarter.

RJ

I've had the same experience with the recoil. I really can't tell a bunch of difference between the 300 RUM and my 8mm Rem mag. The 150's are bombs on deer even at 300 Win and 308 Norma velocities and easily can destroy a front or rear half with bad bullet placement. Perhaps some of the premium 150's would do better, but most of the 150's are designed for 308 and 30-06 velocities.

I'm sure impressed with the RUM's and if I was buying a new magnum rifle for elk here in Idaho it would be either the 300 or as mattsbox99 suggests the 338 RUM. I guess I've always had the mindset that if your going to shoot a magnum shoot the one with the most horsepower. I like the way the heavy 30's, 32's and .338's stop an animal. Recoil can be tamed with a brake if need be or just learning to shoot those big boomers.

That old 8mm Rem mag just sits forlorn in the gun safe waiting to go elk hunting. Years ago I bought out ten boxes of Hornedy 220 grain Game Kings from a store going out of business, boy I've still got a bunch of them left.

I'm not in shape to chase elk anymore, but that's what I'd be shooting if I was. Now here I am oiling the little 280 Remington Mountain rifle spouting off about the big magnums. Whew, don't you guys beat up on me.

Ya know id REALLY like to start reloading. Especially in my 7 rum. Id throw some nosler ballistic tips in that big caseing and i bet id love that.

Lets change the subject alittle. Im just worried that i will end up blowing my self up if i start to reload my own ammo. Is it pretty easy to get the hang of and come up with good powerfull loads??? I just dont want to blow the bolt of my 700 into my face.

7mm reloading using specs from most of the good manuals and a little care reloading is not dangerous. I've been doing that now for 45 years with no problems and my grand daughters, now 13 and 14 have been reloading now for the last four years.

Reloading is simply four easy steps:

1. Resize the case and deprime, done with one die.

2. Reprime the case.

3. Add the correct amount of Powder.

4. Seat a bullet.

Here's my grand babies putting together some quality 243 ammo for their rifles.

http://i136.photobucket.com/albums/q172/faucettb/Reloading/Grandbabiesatbench.jpg

Not only is it easy but most all the folks here will be glad to help you get started.

Think about getting a $79 buck Lee Anniversery reloading kit a Lee and a Lyman reloading manual and some Delux Lee die sets for the calibers you reload. There are several good CD's that take you thru reloading step by step available from Cabela's or Midway. You might start out with one of them. With ammo costs going out of sight this is truly a good time to get into reloading. I cast bullets for my handguns and can shoot for just a little more than the cost of buying 22 lr.

You won't get into trouble reloading if you just pay attention to each step and don't try making the magnums into something they aren't. The data that's available takes them to the limit, and there's no next step in performance. They aren't a .45-70 that was designed for a modification of a converted muzzleloader 134 years ago and that you can boost performance with modern rifles and powders.

If you think the 300 is really walking away, look at the 338... thats all I'm saying, Bob. I've got the 7RUM in a BDL... I like it very much...

I really do like the specs on the 338 Rum and if I were still elk hunting that's the cartridge I would buy. My friend that has the 300 Ultra-mag also has a Remington 7mm STW which is the cartridge Remington had prior to the 7mm RUM and it's killed several deer and elk at long range.

I've got the old 8mm Rem mag in the safe so I'm covered for a long range elk cartridge, but The family of RUM's sure offer a performance gain over everything else on the market. It's interesting that Remington is now making several power levels of ammo for the 300 RUM.

The only thing I don't like about these new high performance cartridges was the early advertising that promoted shooting animals at long range with laser like trajectories. This advertising ignored the fact that long range shooting even with guns with the kind of balistics the RUM's have promote folks shooting way past their abilities.

Even though I shoot a 280 Remington for a deer rifle I've gravitated towards the 30 and over 30 caliber for elk. I've found those 7mm bullets, especially lighter than the 175 grainers at high velocity seem to be much harder for meat destruction than the bigger bores even though some of the premium bonded core bullets will alleivate that somewhat.

I use a 220 grain Sierra spitzer boat tail Gameking in the 8mm mag at 3080 fps. It really works well for both elk and deer even though the furtherst I've shot game with it was 350 yards.

Last year I bought the 280 Rem mountain rifle because the blood thinners I'm on for heart problems makes me bruise really bad from the recoil of that 8mm mag. I still love those big boomers.

That 7mm RUM should be a great gun for that Big Sky Montana country.

Reloading- If I can do it, anyone can do it...

I started with an RCBS partner press, the appropriate dies, a scale and a hand primer about $160.

You can go any color of press you like, the Lee is made from Aluminum, Lyman is a C frame (will flex under heavy pressure) RCBS and Redding use steel O frames. Lots of guys running every press I've mentioned, and thousands of other presses out there that I don't know about.

Thats good. I think it would be pretty cool to reload. Plus theres no telling what kind of performance i could get out of my 7rum with a little bit different bullet. Im think im going to order a good kit to start with and a few manuals, plus ill be asking alot of questions here.

How do you guys usually figure out the best load and grain of powder? Do you ALWAYS follow the manual on the amount of power, or is that how you tweak the load you are making? I Just need to do some research i guess, i just see alot of guys saying how accurate handloads are over factory, how do you go about making them so much more accurate?? Thanks.

You can tweak loads for accuracy by changing powders, amount of powder, bullets and seating depth. The Audette - Newberry method helps zeroing in on an accurate load. Uncle Nick is the expert on it.

Thanks jack. Well what about pressure and water weight and things like that. Will the manual tell me all i need to know about that? Have no idea what water weight is, i just read that a second ago when i searched reloading.

Thats the amount of water in grains that the case will hold. The easiest way to not have to worry about this is to find some reloading data that already starts with the components you want to use, ie. Winchester Brass / Winchester LR primers / Nosler Bullets / Reloder 22 powder / 3.33" COAL

As far as pressure goes, you can't measure that without expensive transducer equipment, so the best thing is to stick to data in a printed manual. The caliber you intend to reload for is well documented.

I personally don't think you need to worry about the water capacity unless you are wildcatting.

I'd suggest reading through a couple of reloading manuals before you get started. If you don't have any friends with manuals, there may be some you can get in the library or via inter-library loan.

Plus there's other useful books, like ABC's of Reloading.

Good luck.

RCBS and several other folks make a DVD that takes you step by step thru learning how to reload. Cabela's and Midway have this and several DVD's on reloading and reloading for long range shooting. Might be a good investment for you.

yea ill check it out. I think i would like reloading alot. Why do you guys do it? What is it that you really benefit from it?? Im not sure that it would be any cheaper for my bigger calibers like the 7 ultra and the 300 ultra if i do buy it.

Say i buy the 300 win mag, would there be any point in reloading that cartridge?? Theres already so many factory bullet selections out there. Fill me in with all the pros of reloading.

Why do I do it?. Hmm, let's see. Well there's the quality time I spend with my boys reloading. There's the cost savings of reloading my own. There's the satisfaction of when I harvest a game animal that I did it with ammo custom made for my rifle, crafted with pride with my own hands.

There's a bunch of reasons, but probably the biggest one is, my Dad started me reloading and casting bullets when I was about 10.

RJ

Once you get the components you need for reloading it will be cheaper per round. I'm reloading the 300 ultra for about $1/round compared to the $3/round factory stuff.

RJ's right on too...there is alot of satisfaction one gets when harvesting game with components that were built from the ground up with your own two carring hands.

For me it is just another way that I can enjoy the sport that I love.

if 300rum is 428 cobra then what is my wbt 30-378. top fuel funny car? i have shot 180gr sierras at 3500+ fps. and with 1-1.5" groups. at 150gr i can get 3600+fps. only draw back is need to reload to afford to shoot

Out of all these calibers mentioned here no one mentioned the 338win mag? I hunted with a 30-06 for many years and a 444marlin in the thick brush. I wanted to bump the 30-06 to something bigger with more knock down power but i wanted something larger than the 30cal bullet. With the 300win specs so close to the 30-06 the 338winmag was my choice back in '94 for a larger more powerful rifle. With 4,000ft.lbs @ the muzzle and it still have the muzzle energy of a 30-06 at 200yds I never looked back yet. As I get older shooting this beast does bother me but i have never had to look for a wounded animal yet, it drops them dead, dead is dead just place your first shot with any caliber. At 100yds benchrested i can put two bullets thru the same hole using new winchester x ammo in my remington 700. With accuracy like that why reload? Of course with the high prices on ammo lately i'll be pushed into reloading soon anyway.

The only thing that keeps me away from the .338 is having to shoot 200 somthing grain ammo and it starts dropping hard out past 300. I would love to own one anyway though, and i bet i will someday

. At 100yds benchrested i can put two bullets thru the same hole using new winchester x ammo in my remington 700. With accuracy like that why reload?


With reloading you can put 5 or 10 shots through the same hole... :D

If all you can get is 1.5 inch groups :o from your "top fuel funny car", I'd say you've got bedding issues or you still need to work on your load. Just my humble opinion.

RJ

i could get much better. 3 holes touching. that was my outside. i have had 1.5" at 200 yd. now my barrel is burned up. another problem with burning 115 grains of powder with each shot

That's one of the reasons I went to the 8mm Rem mag (that bigger bullet thing). With the 300 pushing a 180 grain bullet at 3100 fps It sure seems a big step above the 06 to me though. I hunted a lot of years with a 308 Norma, the ballistic twin of the 300 win mag and several years with the 300 win mag with great results. Living in Alaska for five years led me to Rem's 8 mag with the 220 grain Sierra spitzer boattail loaded to 3080 fps.


I sure agree with the 338 Win mag being a fine cartridge. It's one of the most used calibers in Alaska. I'd probably opt for the 338 Ultra-mag though if I was buying a new one just for the ability to shoot a little flatter.

Do any of you guys have any good ballistic chart software that shows the ballistics on the .325 short mag?? I purchased one awhile back ina a bolt medallion. I know alot of you dont like them and think its just marketing hype, but i still would like to compare the ballistics of it to the 300 mag and other calibers. i love it so far, but ive only made 100-150 yard shots with it(knocks whitetail dead and the silver tips really leave good blood trails if they do run)

I found a few charts but they all have it zero'd at 100 yards, therefore showing it dropping dramatically at 400. I would like to see some charts with a 250 yard zero or somthing along those lines. Is there some sort of formula i could use to figure the ballistics up myself using one of those charts with the 100 yard zero?

You pretty much shot it right out there... its an excellent caliber for sub 200 yard work and destroys deer and elk. Taking 400+ yard shots will require actual field verification rather than guessing it with ballistic charts.

Here's one way to calculate your trajectory with a 250 yard zero. Goto Winchester's website and look up your Silvertip data.
http://www.winchester.com/default.aspx

Specifically: http://www.winchester.com/products/catalog/cfrdetail.aspx?symbol=SBST325S&cart=MzI1IFdTTQ==

OK, they've got a 200 yard zero but you want 250. Helpfully, they've listed the muzzle velocity of 3060 feet per second and the B.C. (Ballistic Coefficient) of .438. There's several online or downloadable ballistic calculators and we'll use Brad Millard's Basic Trajectory calculator.

Plugging in the numbers, we get:

Bye
Jack

Thanksalot jack. Ballistics dont look to bad to me. Anyway back to the new rifle. Still deciding between the 300 win or the 300 ultra.

Here is my chart for the Winchester 220gr Power Points in the .325 WSM.

To me 180's is as light as I'd go in either the RUM or the WM, even on deer. I've seen what 180's from both rifles will do to elk so I can imagine what they will do to deer size game. A 150 from the RUM would plumb scary to shoot deer with. Again, with the 180's a guy has a better choice of options as to bullet construction. You've also got a better ballistic coefficent and sectional density with the 180's v.s. the 150's.

I too have been shooting the 300 RUM for several years now and am very impressed with this round. As a reloader, I've only ever fired the first box thru the rifle as factory loads and everything since has been my reloads. My particular rifle is a stainless 700 and I've had a custom brake installed which I remove while hunting but sure takes the sting out on the bench. It took me allot of powder to come up with a recipe my rifle liked enough for me to hunt with and I ended up loading 180gr TRX's. They gave me what I thought was good groups out to 300 yards (longest range I have) and they shot much better than any other bullet I tried. I eventually got around to trying the 200gr TRX and WOW what a great bullet. For me, this is exactly why I'm shooting a 300RUM. I want to deliver (for me) max payload onto a big (elk, bear)target. I have several rifles I can carry for deer that all perform terrific, but my 300 RUM has an intended purpose.
I have not tried the power level ammo from Remington and probably won't. I think it's a great idea if you only have one rifle and want to do everything, but that's not my particular situation.
As far as recoil, the charts show the 7mm RUM pushing back at 29 lbs and the 300 pushing back at 33 lbs. Not a really big difference. Make the jump to the 338 RUM and that figure jumps (no pun intended) to 43 lbs. Compare that to the 26 lbs of a 300 Win or 17.6 of an 30-06 and at 43lbs you're going to know you've got hold of something. At my age, that's slightly above my pain threshold, but to each their own. I really love my 300 RUM and wouldn't trade it for anything. That's MY nickles worth:)

Great discussion. Other than Remington, which company (firm / gunsmith) builds production rifles chambered in 300 RUM?

Now here I am oiling the little 280 Remington Mountain rifle spouting off about the big magnums. Whew, don't you guys beat up on me.

Traded my .375 in on a pair of .35 Whelen's, a CDL and a 7600, when I detached a retina. And I'd trade my 7mm Mag in on a 280 Mountain rifle if I could find one in good condition.

The older I get, the less I'm impressed with Magnums as a general statement.

So you guys think i will like the 300 ultra even more than the 7 ultra?? I was comparing ballistics on the remington site and with them both shooting 150 siroccos, it showed the 300 ultra just barely having more energy than the 7 ultra up to 300, out past 300 the 7 ultra started spanking the 300 ultra's but.

Others have already pointed out that 180's would be preferable to 150 in the 300. Another note is that comparing a 150 in 7mm to a 150 in .30 cal is not a very good comparison due to greater difference in sectional density. 150 gr is somewhat heavy or midweight for caliber in the 7mm; hence, using the 180 gr in .30 cal against the 150 gr in 7mm would be a more equivalent comparison.

7mmBomb, I have hunted with both the 7mm mag & 300 Win mag for several decades. I also have been shooting the 300 Ultra Mag since it hit the market! I have a wildcat .338/300 Ultra mag as well.

Now big caliber's do a better job on bigger game like elk, bear, moose etc. However, one must NOT forget that bigger doesn't always bring about the best turn of events, if one can NOT handle the recoil and produce the proper accuracy from that shoulder cannon your aimming down range with OK.

Now 5 lbs of recoil to the shoulder area is something that 90% of most hunters will indeed notice, when going up the scale in power, bullet weight and caliber. The average male can handle between 22 and 26 pounds of "Felt Recoil" after that things start to make you start to flinch, even though you may not believe you are.

It takes a lot of time, effort and good practice to be able to just jump form a caliber like the 300 Win mag, dishing out 27 to 32 pounds of felt recoil depending on the load and bullet weight, to using a 300 Ultra mag which put out as much recoil as a .375H&H (44 pounds & upward).

My advice is to stay with the .300 Win mag caliber verses the 300 Ultra mag! You will be able to shoot it a whole lot more accurate down range and that is the name of the game.......Putting the bullet in the bulls eye or vital zone of the big game animal your trying to kill.

My 300 Win mag, using a 180 grain bullet at the veloctiy of 3130fps was all the rifle I could handle at my younger age and body weight of 165-lbs. I been shooting my .338 Win mags for the last 20 years but I weigh in at 225-lbs nowdays and the recoil feels about the same with 250 grain bullets, only it is not really at 34-lbs.

Good Luck on your choice of calibers OK. By the way, my target rifle at the bench, is a 7mm Rem. mag, it hands out 25-lbs of recoil using my reloads and Sierra bullets.

sorry to bring this from the dead, i never did get a chance to purchase a new rifle, but i am now in the market again. I think i have decided on the .300 rum. Now i just need to decide on which rifle. Correct me if im wrong, but no other gun company makes an ultra mag besides remington right? I would love to have a browing medallion in this caliber. is there any way to custom order this caliber from browning without spended an arm and a leg?

If remington is my only option im going to be torn between the good looking classic 700 bdl with the glossy wood stock and barrel, and the sendero. I have shot the sendero and love how it shoots but its just so big and bulky and im not all that fond of its look. But im just worried about how accurate the 700 bdl will be. Id rather have a very accurate rifle even if it doesnt look as pretty.

One other thing, i found out recently that remington does produce the 700 LSS any more? Well i think they make a wood color version, maybe its called mountain rifle or somthing? But the one i own (in 7rum) is laminated in more of a grey-ish green color. Its hard to explain but im sure you guys know what im talking about. Anyway i wish they still made that model, i wouldnt hessitate to buy another one.


Sorry for the long post, and bringing this old post back, just figured you guys could help me decide on with model rifle i need the most. Thanks.

Id rather have a very accurate rifle even if it doesnt look as pretty. Think your odds of getting an accurate BDL are about the same as the Sendero. Maybe I'm wrong. But the BDL would be easier to carry for hunting purposes.

Good luck.

7mmbomb you can get the 700 in the following models

BDL,
CDL,
SPS,
SPS Stainless,
Sendero SF II,
XCR and
XCR REMF edition.

That seems to be 8 models of the 700 avialable in 300 Ultra-mag. Here's where to check on them.

http://www.remington.com/products/firearms/

I personally like the CDL's ergonomics really well, but do suggest a muzzle brake on them. You can get any number of folks to build you a custom 300 Ultra-mag. A friend just got one from Christianson Arms. It was about 3400 bucks in the configuration he ordered. I'd sure suggest getting a mizzle brake, of the three I've shot two had the brake including the 6.5 pound Christianson and they were very pleasent to shoot.

I shoot several Remington's and have had pretty good luck with them. If I didn't already own a classic in 8mm Rem mag I'd sure have one of the Ultra-mags. Probably the 338. I shoot a 280 Remington Mountain rifle along with a VLS 243 and a Model 7 308 Carbine and am pleased with them.

There is a free ballistics program available for download at: www.huntingnut.com (http://www.huntingnut.com) called "Point Blank Ballistics". One enters the bullet weight, diameter and ballistics coefficient, the sight in distance, and the muzzle velocity to get a predicted trajectory. It also generates a table of effective ranges for various big game species based on "Taylor's KO Factor". Even though the trajectories need field verification and one may not agree with the assumptions inherent in Taylor's equations, it can be interesting to compare different cartridges and bullets.
